NOTIFICATION  
Addendum  
The following communication, received on 17 October 2023, is being circulated at the request of the 
Delegation of Switzerland . 
 
_______________  
 
 
Ordinance on the placing on the market of phytosanitary products (Ordonance sur la mise en 
circulation des produits phytosanitaires)  
The Ordinance on phytosanitary products (RS 916.161, OPPh ) was notified in document 
G/SPS/N/CHE/82 of 19 December 2019. The OPPh establishes conditions for the placing on the market 
of phytosanitary products. Annex 1 to the OPPh contains a list of active substances that may be used 
as phytosanitary products in S witzerland. A new substance is included in this Annex if, once the 
application accompanying the request has been examined, it meets the conditions established in 
Article 5. The following amendment of the OPPh includes three new chemical substances: Kieselg ur 
(diatomaceous earth), Mefentrifluconazole and Oxathiapiprolin. The substance Kieselgur 
(diatomaceous earth) replaces the substance siliciumoxyde previously listed in this Annex, which is 
accordingly deleted from the Annex. Kieselgur (diatomaceous earth)  better describes the substance 
currently contained in the approved plant protection product with siliciumoxyde and thus also 
corresponds to the equivalent designation in the EU. One microorganism (Bacillus firmus) is deleted 
from the Annex for formal reas ons. For the substance Cydia pomonella Granulovirus there is a formal 
change to the name as well the addition of the classification as a "low -risk substance". These 
amendments are in alignment with EU decisions and regulations. Details are stipulated in th e attached 
draft document.
